3. OverDrive Plus (ODP)
OverDrive Plus (ODP)是一種全新技術(shù),從 Boulder 非線(xiàn)性系統(tǒng)(BNS)專(zhuān)門(mén)為Meadowlark 光學(xué)反射空間光調(diào)制器(SLMs)設(shè)計(jì)。當(dāng)使用我們的 SLMs ODP時(shí),連續(xù)全息圖之間的相變時(shí)間將大大減少。使用ODP顯示降低2 - 8 x 標(biāo)準(zhǔn)的光學(xué)響應(yīng)時(shí)間。這個(gè)響應(yīng)時(shí)間減少歸功于三個(gè)獨(dú)立的技術(shù)開(kāi)發(fā)集成在一起的組合產(chǎn)品: Transient Nematic Effects, Phase Wrapping and Regional Look‐up‐ ables。
